Abstract

The communication performance aspects of a PACS in the department of Radiology in a hospital of reasonable size were investigated by means of an analytic model. Assuming a realistic load in number of newly generated images and reporting by radiologists, it turns out that the system can be designed in such a manner that a communication speed of 8M bytes/sec will be sufficient. In such a system much attention must be given to pipeline the operation of many processes. This applies to the design of the ACR-NEMA communication layers and to the fetching and storing of messages on disks (application layer). In turn, operations in the application layer can only run in parallel if the short Commands will be given transmission priority in the communication net, in order to set up the fetching of a message from disk as early as possible. Parallel operation also requires the provision of buffer memories at the workstations and acquisition devices.
